Mihai Chira resolved FLEX-35025.
--------------------------------
Resolution: Fixed
> Validator results cannot be intercepted if the value is null
> ------------------------------------------------------------
>
> Key: FLEX-35025
> URL: https://issues.apache.org/jira/browse/FLEX-35025
> Project: Apache Flex
> Issue Type: Bug
> Affects Versions: Apache Flex 4.15.0
> Reporter: Mihai Chira
> Assignee: Mihai Chira
>
> {{mx.validators.Validator.validate()}} usually ends up passing its
> {{ValidationResultEvent}} through {{handleResults()}}. However, in an edge
> case (when the value it's validating is {{null}}) it dispatches the
> {{ValidationResultEvent}} without passing it through {{handleResults()}}.
> The scenario is: we need to set the {{field}} property on the
> {{ValidationResultEvent}} before it leaves the custom validator. This is
> impossible for the (correct) situation when the value that's being validated
> is {{null}} (which, in our custom validator, is a valid value).
